Abstract: ABSTRACT OF THE DISCLOSURE             A pollution control method for reducing the pres-ence of contaminants in stack gases from the manufacture of glass fiber wool-type products includes feeding the forming fan gas into a centrifugal fan and injecting massive quantities of water into the fan intake.  The aerosol particles are agglomer-ated by impact with the airborne droplets of the water and wet surfaces of the fan.  The larger, coalesced or agglomerated particles are more readily susceptible to inertia-type separa-tion from the air by the action of the fan and in a later sep-aration operation.  It has been found that 1.5 or more gallons per minute of injected water per thousand standard cubic feet per minute of forming gas passing through each fan is effect-ive to remove more than 40% of the contaminants and even larger amounts of water remove greater amounts of such particles.          Further, the process water can be recirculated, thus reducing or eliminating the consumption of fresh water and maintaining the normal process water system of the manufacturing operation.

Abstract: SPIRIT LEVEL WITH TOP  WINDOW MOUNTING Abstract of the Disclosure A spirit level having an I-beam type frame with an opening in the web for mounting a vial assembly for viewing a bubble vial from the side.  The vial assembly includes a dummy portion and a vial holding portion.  An opening in a flange of the frame is adapted to provide a window for vertical viewing of the vial.  A window element includes elongated upper and lower windows, with the upper window extending into the opening in the I-beam flange and the lower window being received by a recess in the vial assembly.  A pair of locating ledges are disposed between the upper and lower windows and extend outwardly from the peripheries thereof.  The ledges are separated by end slots which recieve a cut-out web portion of the I-beam frame. When the upper window is disposed in the I-beam flange opening, the dummy portion of the vial assembly is positioned on one side of the web and holds the window element tightly in position against the flange.  However, when the vial holder is placed on the opposite side of the web, a slight space is provided between the vial holder and adjacent ledge, thus permitting rocking adjustment of the vial holder before it is tightened to the web.

Abstract: ABSTRACT      This invention relates to a process for producing crystalline silicon having an iron concentration less than the iron concentration of the mother liquor.  Iron contamin-ated silicon is introduced into a mold and the mold walls are maintained at a temperature sufficient to cause silicon crys-talline growth.  The mother liquor is agitated to wash the exposed surfaces of the growing silicon crystals and to pre-vent the freezing of the top surface of the mother liquor.  A hollow crystalline silicon ingot is formed and both the inner zone centrally of the crystalline ingot and the outer zone ad-jacent to the mold wall are discarded.  The remaining central crystalline portion of the ingot has an iron concentration of from about 1/20th to 1/100th of the iron concentration of the mother liquor.

Abstract: Abstract Volumetric fluid flow in a cylindrical conduit is determined by measuring the average flow velocity or the fluid flowing through a chordal measuring path lying at a radial distance of 0.54R where R is the radius of the con-duit. This average flow velocity is multiplied by constants related to the location or the chordal path and to the chordal path length.  The average flow velocity measurement is made by the use of an ultrasonic flow meter having upstream and downstream transducers which define the chordal measuring path, Multiple measuring paths are preferred.

Abstract: TITLE OF THE INVENTION:  Castered Load-Transfer Axle Stabilizer INVENTORS:  William J. Mohrbacker & Earl C. Thayer ASSIGNEE:  REXNORD INC., a Wisconsin corporation ABSTRACT OF THE DISCLOSURE:           The load supported and transferred by the rear auxiliary axle of a truck is commonly determined by the fluid pressure supportively disposed between the auxiliary axle and the rear end of the truck frame.           Where the auxiliary axle is some distance to the rear of the truck for that purpose, the wheels are castered to avoid scuffing.  The castering, however, must gen-erally be damped to avoid fluttering of the wheels and shimmying of the axle.  Frictional damping means which is here disclosed is both adjustable and varied auto-matically with the amount of such pressure and the amount of load transformed.  In particular the sta-bility of the vehicle is greatly improved.

Abstract: ABSTRACT OF THE DISCLOSURE      A gang mower having a main frame and a number of individual mower units connected to the main frame. Each mower unit has a pulley driven by a drive belt which extends to a pulley on the main frame, to drive the mower unit reel. A telescopic arm is rigidly connected to the mower unit, extends between the flights of the belts, and is pivotally connected to the main frame between the pulleys.  A support strut extends from the telescopic arm to the outer end of the mower unit frame to help align the mower unit.  A rear support arm extends laterally from the rear of the mower unit to the main frame to guide the rear end of the mower unit while allowing it to rise and fall.  A bias spring exerts downward pressure on the rear support arm to counteract the lifting torque of the drive belt, thereby ensuring that the mower unit will cut at the same height at each of its sides.

Abstract: VARIABLE DISPLACEMENT COMPRESSOR WITH          THREE-PIECE HOUSING          Abstract of the Disclosure A wobble plate compressor including a three-part housing in the form of a front shell-like section, defining a wobble plate mechanism cavity, an intermediate cylinder block section and a rear head section, all of the parts being connected in series such as by elongated cap screws.  A blind bore in the first section end cover receives a piston to define an expansible chamber actuator.          Passage means are formed in the housing for conducting hydraulic fluid from the housing sump to the inlet of pump means.  Hydraulic liquid outlet passage means, providing a flow passage between the front and rear heads, are formed in the housing such that control valve means in the rear head can affect the flow of the liquid or oil from the sump to the expansible chamber, causing the modulating piston to vary the angle of the wobble plate mechanism and thus the pumping capacity of the compressor.  A generally spherical guide shoe is mounted in an axial shiftable manner on a guide pin projecting radially from the wobble plate with the spherical shoe slidable between a pair of opposed cylindrical guides whereby a line contact is maintained between the spherical guide shoe and the cylindrical guides to prevent rotation of the wobble plate element while permitting angular movement thereof relative to the drive shaft.
